Scotland: scheduled monument consent in practice

This article is about Scotland. Scheduled monument consent is a separate consent from planning permission, granted by Scottish Ministers and administered by Historic Environment Scotland, and you need it before carrying out almost any works to a scheduled monument. The duty comes from the Ancient Monuments and Archaeological Areas Act 1979 as it applies in Scotland. Carrying out works without consent is a criminal offence, which puts scheduled monument consent Scotland in a different category from most planning questions a landowner deals with.

Planning permission does not cover you. Neither does the fact that the works are agricultural, or that the monument is unrecognisable as anything on the ground.

What scheduling protects

A scheduled monument is a site of national importance entered in the schedule maintained for Scotland. Scheduling protects the monument and the ground it sits in, which is the part owners find counter-intuitive, because the archaeological interest is usually below the surface rather than visible above it.

Field systems, souterrains, brochs, cairns, deserted settlements, industrial remains, military structures and earthworks with no standing fabric at all are all represented. A flat grass field can be scheduled.

The schedule entry defines the extent by a mapped boundary. That boundary is the thing to check before any work, because the scheduled area is often larger than the visible feature and can extend into an adjoining field.

Which works need consent

The Act requires consent for works resulting in the demolition, destruction, damage, removal, repair, alteration or addition to a scheduled monument, and for flooding or tipping operations on the land in, on or under which it sits. That list is wide enough to catch work that nobody would describe as development.

Routine operations that commonly need consent include:

• Deep ploughing, subsoiling or any cultivation deeper than previously practised
• Installing a new fence line, gate post or water trough within the scheduled area
• Laying a track, pipe run, cable or drain across the monument
• Tree planting, and felling where stumps will be removed
• Erecting or removing a building, wall or hard standing
• Metal detecting and any excavation, including for an archaeological trial trench

A class consents order grants consent for specified categories of work, and the usual example is agricultural cultivation of the same kind and to the same depth as has been carried out in the preceding years. Do not rely on a class consent without checking its current terms, because the scope is narrower than it sounds and a change in depth or method takes you outside it.

Who decides, and how long it takes

Applications are made to Historic Environment Scotland, which handles the casework and advises on the decision taken on behalf of Scottish Ministers. There is no fee for scheduled monument consent.

Timescales depend on complexity and on whether an archaeological evaluation is needed to understand what the works would disturb. Allow for a pre-application discussion, which is free and worth taking up, and for the possibility that the answer is a different design rather than a refusal.

The decision can be a consent, a consent with conditions, or a refusal. Conditions commonly control the method, the timing, the supervision and the recording.

Evidence that supports an application

The application has to let the decision-maker understand the effect of the works on the monument. Three documents do most of that work.

1. A location plan showing the scheduled boundary, taken from the schedule entry rather than drawn by eye, with the works plotted on it
2. A method statement describing exactly how the work will be done, including depths, plant, access routes and where spoil will go
3. A statement of significance explaining what the monument is, why it is important, and what the works would affect

Depth is the single most useful number you can give. A fence post driven 600mm into a souterrain is a different proposition from one set in an existing post hole, and an application that states the depth, the diameter and the number of posts can be assessed without a site visit in many cases.

Where the ground has already been disturbed, say so and show the evidence. Previous service runs, quarrying or modern made ground reduce the archaeological potential of the specific footprint, and that is an argument the applicant has to make rather than one the regulator will find for you.

An illustrative example

A farm track needs upgrading, and 40 metres of it crosses the edge of a scheduled field system. The options are to re-route the track outside the scheduled area at greater cost, to construct over the existing surface using a geotextile and imported material with no excavation, or to excavate a formation and accept an archaeological watching brief. The details are illustrative.

The middle option is usually the one that gets consent, because building up rather than digging down preserves the deposits in place. It also tends to cost less than re-routing. The lesson generalises: a design that avoids excavation is worth more to this application than any amount of mitigation offered afterwards.

Archaeological conditions and recording

Where disturbance is unavoidable, consent is likely to carry conditions requiring a written scheme of investigation agreed in advance, work supervised by a suitably qualified archaeologist, and a report deposited with the regional archive and the national record.

Budget for the post-excavation work as well as the site attendance. Specialist analysis, illustration, reporting and archive deposition routinely cost more than the days on site, and a condition requiring a report to be lodged before a subsequent stage of works can hold up a programme if the funding was never allowed for.

The archaeologist should be appointed before the application, not after the consent. Their input usually improves the method statement enough to narrow the conditions.

Where planning permission fits

The two consents are independent. A proposal can need planning permission from the local planning authority and scheduled monument consent from Scottish Ministers, and getting one says nothing about the other. Neither is a prerequisite for applying for the other, although it is sensible to resolve the monument question first, because a redesign to protect the monument will change the drawings the planning application relies on.

National Planning Framework 4 contains the national policy on historic assets and the local development plan will add to it. Scheduled monuments attract the strongest protection in that framework, and the test is weighted heavily against disturbance.

The Scottish consent regimes run on their own categories and procedures, and the listed building system is the other one owners meet most often, set out in listed building consent in Scotland. Which authority deals with an associated planning application depends on the development hierarchy, as the hierarchy of developments in Scotland explains, and community priorities may be recorded in a local place plan, covered in local place plans in Scotland.

Enforcement and offences

Executing works without consent, or in breach of a condition, is an offence under the 1979 Act, and so is damaging a scheduled monument. There are also powers to require a site to be put right.

Ignorance of the schedule is a weak position. The boundary is a matter of public record, and a contractor's mistake will land on the owner who instructed the work. Put the scheduled boundary on the drawings issued to the contractor and mark it on the ground before plant arrives.

PlanScope's drafting is grounded in English policy and procedure, so a Scottish application needs the reviewer to check the draft against National Planning Framework 4 and Scottish consent procedure. Browse the report types to see which supporting documents a scheme near a designated asset usually needs.

This is general guidance, not legal advice. Check the position with Historic Environment Scotland, the planning authority or a qualified professional before relying on it.
